ASA 129th Meeting - Washington, DC - 1995 May 30 .. Jun 06

Turbulent flow along a structural boundary acts as a source of noise to
the interior space. Characteristics of the transmitted noise are determined not
only by the turbulent flow field but also by the transmission characteristics
of the bounding structure. In low-speed flow applications, the spatial scale of
the turbulence can be smaller than the structural wall thickness. Under this
circumstance, thickness effects are important in modeling the wall
transmissibility. These effects are examined using the elasticity solution for
the axisymmetric response of cylindrical shells. Results are presented for
steel-like and rubber-like wall materials and compared with results from thin
shell theory.
